			This quick tutorial will help you to setup your SSH keys and use them with your Enos.itcollege.ee space.

	Secure Shell, or SSH, is a cryptographic (encrypted) network protocol to allow remote login and other network services to operate securely over an unsecured network (no clear text). You can SSH to Enos using your password, but having the secure keys setup goes faster if you have to login many times (and it looks cool).

	With SSH, you generate two keys: one Public and one Private. The public key is not secret, anybody can have it if they want to. Whereas your private key is very important and must not be shared! Your public key is not secret because it must be stored in each server/computer/device you will want to access with your private key. The public key is like the same lock that you install at the front-door of all your houses/apartments (suppose you have many). To enter all those houses/apartments you only need your private key (which only you possess).		With SSH, you generate two keys: one Public and one Private.

	That's it! Now you can access your Enos space without entering your password: <code>ssh ''your-itcollege-username''@enos.itcollege.ee</code>		That's it! Now you can access your Enos space without entering your password: <code>ssh ''your-itcollege-username''@enos.itcollege.ee</code>
